Pacman v4.1.2-460-ga0cfed-dirty - libalpm v8.0.2

if you get this:
==> ERROR: Unknown download protocol: hg
even though you used: makepkg -s
and makedepends contains mercurial
you have to manually: pacman -S mercurial
then continue and run: makepkg -s

this may or may not be due to the --incremental patch
